How do I fix a wPay pinpad producing "Bank Unavailable" or "Certificate Expired" error

WPAY terminals are experiencing problems with the auto-renewal of digital certificates, which is supposed to occur 28 days before expiry.  Wpay have / will fix auto-renewal, though we need to address the affected pinpads manually on this occasion

Identification:

1) The custimer may call in with either "Bank Unavailable" or "System Error" on POS screen.

Example of error message on POS

Resolution

1) Attempt manual certificate update

• Switch the pinpad to standalone mode and perform a logon.

• If the certificate is expired, press #99 and restart the terminal to attempt an automatic update.

• If the terminal does not update, ensure it is connected to WiFi or LAN and reboot it.

2) Reset and Re-board the Device

• If the issue persists, contact Oolio who will get a new certificate from Wpay. You will be provided with a new TID (Terminal ID) to go with the existing MID (Merchant ID)
